Hello,
I have a problem with initializing connection with IMU while using MPU-9250. I am suspecting the possibility of the module being damaged/flawed in some way. I am using an example code given by the IvenSense MPU9250 library, and no matter what, I am getting an error message on the serial monitor Error initializing communication with IMU. Sometimes the error cuts out a ouple of letters which looks like: Error initializing coation with IMU or Error initializing comtion with IMU, however I don't know if it makes all the difference. i will provide you the code and wiring below. I am also using a logic level converter for I have been advised to use that whilst connecting the MPU-9250 to the Arduino UNO. Wiring and code is below.
Code:
